Application filed October 5, 1926. serial no. 139,695.

This invention relates to certain improvements in anchors and it is anobject of the invention to provide a device of thiskind for use inconnection with guide lines or the like for telegraph poles, etc, andwherein means is provided to effectively apply the anchor in workingposition;

The invention also has for an object to provide an anchor comprising aplate carrying a plurality of pivotally supported looking arms togetherwith means for causing said arms to extend into desired workingposition.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved anchorwhereby certain important advantages are attained and the devicerendered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to de-' scribe the same with reference to the accompanyingdrawing, wherein Figure 1 is a view in top plan of an anchor constructedin accordance with an embodiment of my invention, the rod being shown insection and the locking arms extended;

Figure 2 is a view in side elevation of the device as illustrated inFigure 1 with the arms in their raised or inoperative position;

Figure 3 is a view partly in side elevation and partly in sectionillustrating the arms in extended or locking position;

Figure 4- is a view in top plan of the plate fixed to the rod.

As disclosed in the accompanying drawing, 1 denotes a circular plate ofrequisite diameter and which is provided therearound in its peripheralportion with a series of equidistantly spaced open slots 2, the sidemargins of which being defined by depending lugs 3.

Pivotally supported between each pair of lugs 3 by the bolt 4 or thelike is an end portion of an elongated arm 5 disposed on a predeterminedincline and which extends above the plate 1. The pivoted end portion ofthe arm 5 is provided with a tail extension 6 extending inwardly of theplate 1.

The contact of the tail extension 6 with the under surface of the plate1 limits the extentof outward and downward swinging movement of the arm5.

At its axial center the plate 1 is provided with an opening 7 throughwhich is freely directed an elongated rod 8. This rod 8' has its lowerend in threaded engagement with the axial center of a second plate 9 ofa diameter less than that of the plate 1 and which is adapted to havecontactwith the tail extensions 6 to cause the arms 5 to swing outwardlyinto working or locking position.

In practice, my improved anchor is placed within a suitably formed holeand when in desired position the contact of the tail extensions 6 withthe plate 9 will cause the arms 5 to swing outwardly and downwardly intocontact with the wall of the hole. Uponrequisite pull being imposed uponthe rod 8 the arms 5 will penetrate the wall of the hole and therebyassure an effective locking of the anchor.

The upper surface of the plate 9 has disposed substantially radiallythereon a ridge 10 which is adapted to receive a tail extension 6 tohold the plate 9 against rotation when it is desired to unscrew or freethe rod 8 from such plate 9. This is of advantage when it is desired toreclaim the rod when discontinuing the use of the anchor.

From the foregoing description it is thought to be obvious that ananchor constructed in accordance with my invention is particularly welladapted for use by reason of the convenience and facility with which itmay be assembled and operated, and it will also be obvious that myinvention is susceptible of some change and modification withoutdeparting from the principles and spirit thereof and for this reason Ido not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice except as hereinafter claimed.

I claim 1. An anchor of the class described comprising a rod, a platefreely slidable thereon, arms pivotally engaged with the peripheralportion of the plate, each of said arms having a tail extensionextending inwardly of the plate, and a second plate carried by the rodbelow the first named plate and tail extensions for contact with suchextensions to swing the arms outwardly into working position.

2. An anchor of the class described comprising a rod, a plate freelyslidable thereon, arms pivotally engaged with the peripheral portion ofthe plate, each of said arms hav- 4 'ing with a tail extension to holdthe second plate against rotation to permit unscrewing of the rod fromthe second plate.

An anchor of the class described comprising a rod, a plate freelyslidable there on, arms pivotally engaged with the peripheral portion ofthe plate each of said arms having a tail extension extending inwardlyof the plate, a second. plate threaded upon the rod below the firstnamed plate and tail extensions for contact with such extensions toswing the arms outwardly into Working position, said second plate havingmeans coacting with a tail extension to hold the second plate againstrotation to permit unscrewing oi the rod from the second plate, saidmeans comprising a ridge in a face of the second plate opposed to thefirst plate to receive a tail extension.

In testimony whereof I hereunto afiix my signature.
